A direct measurement of the magnitude and sign of the quadrupole moment of the carbon dioxide molecule has been made by determining the birefringence induced in gaseous C02 by an inhomogeneous electric field. The method of measurement and the experimental details are described. The observable is the product of the molecular quadrupole moment 0 and the difference between parallel and perpendicular components of the optical polarizability tensor. F o r CO2, this quantity was found to have the… 
Measurement of the electric quadrupole moments of CO2, CO, N2, Cl2 and BF3
The electric quadrupole moments of a number of molecules have been determined from measurement of the birefringence induced in a gas by an electric field gradient. The values obtained are: carbon
Measurement of the electric quadrupole moment of CO.
It is demonstrated that in the case of carbon monoxide, quantization of the rotational motion of the molecules needs to be considered, and the analysis yielding a quadrupole moment of Θ = (-8.77 ± 0.31) × 10(-40) C m(2) and a hyperpolarizability term of b' = (-0.0078) ×10(-60) C(3) m(4) J(-2).
Measurement of the electric quadrupole moments of CO 2 , CO and N 2
Values for the traceless electric quadrupole moments of carbon dioxide (-13·4 ± 0·4 × 10-40 C m2), carbon monoxide (-8·58 ± 0·35 × 10-40 C m2) and nitrogen (-4·72 ± 0·26 × 10-40 C m2) are deduced
Measurement of the electric quadrupole moments of CO2 and OCS
The electric quadrupole moments of carbon dioxide and carbonyl sulphide have been measured via the technique of electric-field-gradient-induced birefringence (the Buckingham effect). Measurements for
Measurement of the electric quadrupole moment of N2O.
The temperature-independent term, previously assumed to contribute negligibly to the EFGIB, is found to contribute some (5.2 ± 0.6)% to the effect at room temperature and clearly needs to be accounted for if the quadrupole moment is to be definitively established.
The quadrupole moments of dipolar molecules
The electric quadrupole moment of a dipolar molecule depends upon the molecular origin from which it is measured. An electro-optical method has been successfully used for measuring the quadrupole
The quadrupole moment of chlorine
The molecular quadrupole moment of chlorine was determined by measuring the refractive index anisotropy induced in the gas by an electric field gradient. A value of 5·0 ± 0·5 × 10-26 esu was found

A number of simple pair interaction potentials of the carbon dioxide molecule are investigated and found to underestimate the magnitude of the second virial coefficient in the temperature interval
A method of measuring electric quadrupole moments of molecules in excited states
A method is proposed for measuring electric quadrupole moments of atoms and molecules in excited states by observing electric field gradient induced birefringence (quadrupolar birefringence) in
Higher Polarizability of the Helium Atom
The electric dipole moment induced in a helium atom by a uniform electric field F can be expressed by αF+⅙γF3+···, where α is the well‐known electric polarizability, and γ is a higher polarizability


Direct Method of Measuring Molecular Quadrupole Moments
An experiment whose object is the determination of permanent molecular quadrupole moments is suggested. It is analogous to those used in measurements of electro‐optical Kerr constants, but the

The quadrupole moment of a hydrogen atom in a general state induced by a uniform electric field has been evaluated to second powers of the field strength. It is also shown that a uniform magnetic

In an earlier paper I showed that the light scattered by gases free of dust was not perfectly polarised, but that a residual defect of polarisation remained, which was characteristic for each gas.
